IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 218,407, dated August12, 1879; application filed November 5, 1878.

To all whom it may concern:

Be it known that I, COLUMBUS STEPHENS, of Cave Spring, in the county ofFloyd and State of Georgia, have invented a new and useful Improvementin Cultivators, of which the following is a specification.

Figure 1 is a side view of my improved plow, partly in section, to showthe construction. Fig. 2 is a top view of the same, part being brokenaway to show the construction. Fig. 3 is a detail section taken throughthe line a :r, Fig. 1.

Similar letters of reference indicate correspondingparts.

My in vention is an improvement in the class of cultivators whose beamsare so connected as to adapt them for lateral adjustment, and which havepivoted adjustable standards.

Theimprovements relate to the construction and attachmentof the bracesfor the standards, as hereinafter described and claimed.

A indicates the two iron beams of my cultivator, and B the clevis-block,and O the clevis. The beams are connected by transverse rods E, to whosescrew-threaded ends nuts F, havin g handles f, are applied, for thepurpose of enabling the beams to be adjusted laterally. About theconstruction and arrangement of these parts there is nothing new.

The standards D are pivoted to beams A and supported by braces G.

The braces G are curved upward and forward and then upward, and theirupper ends are bent over laterally into hook form, to hook over theupper edges of the beams A, as shown in Figs. 1, 2, and 3, where theyare secured in place by set-screws H, which pass through them and bearagainst the sides of the said beams A.

Several indentations are formed in the sides of the beams A to receivethe points of the set-screws H, so that the forward ends of the braces Gcan be readily adjusted to give any desired pitch to the standards D.

I are the plows, which may be shovel-plows, bull-tongues, scrapers,turn-plows, or any other kind of plow, as the work to be done mayrequire. Said plates are secured to standards D by screw-bolts J andT-headed bolts K. A slotted plate or washer, L, is applied on the rearside of the standards to hold the bolts J K a proper distance apart.

I am aware that braces for standards have been adjustably connected tothe beams of a cultivator, and I do not claim such combination orarrangement of parts.

What I do claim is As the improvement in cultivators hereinbeforedescribed, the combination, with the standards D and the beams A, havingone or more rows of indentations, as specified, of the braces G, havingtheir upper ends made hookshaped to embrace the beams, and the setscrewsH passing through said braces opposite the row of indentations, all asand for the purpose set forth.

COLUMBUS STEPHENS.
